I have the Tmobile version of he S3 and would like to know when I travel out of the country later this year would the phone work through roaming if I wanted to use it? Is there a way to disable the roaming and still use the phone through wifi? I just don't want to rack up a huge bill. Thanks, any help is appreciated.

Hi,
I've got an HTC Hero from Orange UK. I'm very pleased with the phone so far, but soon I'll be going on holiday in the US. When I go, I was planning to unlock the phone and use an alternative provider while in the US for both voice and data. From what I've read, I'll be limited to GPRS for data rather than 3G, since the Hero100 only supports UMTS1700 (listed as 'Future' US) and UMTS2100 (just about everywhere else) for 3G. I would need UMTS1900 to get 3G access in the US, is that right? Presumably this is a hardware issue with the radio itself?
If I am limited to GPRS, no problem - as long as I know there's no way I can get any kind of 3G while I'm over there. Can anyone recommend a good temporary provider who will sell me the US equivalent of a pay-as-you-go SIM for phone and data? And, might all these questions be irrelevant if I'm going to have loads of problems flashing the radio ROM so that the phone will allow me to use another provider?
Thanks in advance,
Rob
I dont think you would have to anything to the phone besides just unlock it. T-mobile and att I believe both have pay as you go plans and prepaid services you should check their us websites to find out more.
There is no pay-as-you-go data in the US on GSM networks except for crazy $$$/kb fees. Major inconvenience.
There are prepaid tarifs where you pay your monthly fee in advance rather than afterwards; They are called Flexpay (t-mo US) and Pay as you go (AT&T) iirc. Then you are kindly allowed to add data packages on top of your plan. But you can't stop paying for a few months when you are outside of the US or the whole thing gets cancelled...
I am new and I could not post this as a reply to this thread: http://forum.xda-developers.com/showthread.php?t=1109983 in the Developers section so I created a new thread here.
I called AT&T CS and the rep told me that I needed a new sim card to access the 4g network and to call when I receive it in a few days to call back and change my iphone unlimited plan to the smartphone unlimited plan. He said to only speak to a supervisor in order to keep my unlimited plan. Just feels risky. I live in San Antonio TX and he assured me that HSPA+ is defintitley working here and LTE is actually working although I don't think there are any devices available from AT&T right now that support LTE. I currently get 3-5mbs on Speedtest and I am wondering if i will even see a difference with new sim card. Is it worth even switching to smartphone plan? I don't wanna risk loosing my unlimited plan if i am not going to see any difference in speed anyway. Any thoughts?
I have the unlimited data plan with at&t , Im getting H+ with my old 3g sim card. with up to 6mbp Supposed to be getting 7 . I dont think you need a new card for 4g? Not sure tho dont take that for fact It might be true! Most Att store employes Dont know what the hell there talking about. They do more screwing you then helping you. Keep your sim and dont tell them you are switching phones. Wate for more info from people here before you decide
Bump.. Any info?
If you search, you'll find several topics on this. Short story, you do not need a new SIM card, but in order to get the full speeds of HSPA+, you will need to provide AT&T with an IMEI number from a AT&T 4G phone. You can't use the Galaxy S2 IMEI because it's not a USA based phone, and it's not in their database. Just look up an IMEI for an Atrix or some other 4G phone (you can go to the AT&T store and look up the number on the floor model if you want) and give it to them. It doesn't need to be unique. Tell them you got an Atrix, not a Galaxy S2.
You should speak with a supervisor to retain your unlimited plan, or else they might switch you to a limited plan.
Otherwise, you can stay as you are, and you can access HSPA+, but not the full speed (assuming you're in an area that has the full speeds available).
As the subject stated: I am planning to unlock my AT&T Galaxy Note to use it in Japan, but not sure if the Note will work there. I just want to be able to make calls and do light browsing at 3G speed (not 4G LTE)
Japan have 3G GSM network, so it should be, But want to confirm before I spent the $$$ unlocking my AT&T Note.
it has the proper frequencies for cellular use on 3g idont know about hspa+ so prbly dataspeeds around 2-5 mbps

Thank you for the information!
What kind of prepaid SIM are you going to use in Japan? I couldn't find any SIM that has prepaid voice and data together. So I'm planning to use b-mobile 1GB data plan with fusion IP phone SMART. That way, I can send/receive phone call and use data.
Did you have any luck? I can't get the bmobile sim to work with this phone. Urgent help needed. I suspect it takes some special config or different radio but I don't know. The bmobile instructions alone don't work.
Look up APN for bmobile. Just my 2 cents.

I had all the correct settings. I suspect the card did not work with Android 4.12. I have seen references online to rolling back to 4.11 for possibly unrelated or possibly related issues. They would not refund, so I had to do a charge-back on the card. Never trust a company who fails to stand behind a product when it completely fails to work. I ended up paying the higher price for AT&T which worked well except don't trust their wifi app - it tries to connect to partners who aren't partners, which disrupts the otherwise working mobile data connection.
Well, that really sucks, man. I guess your best shot would be to try and find another carrier that is GSM if the roll back to 4.1.1 doesnt work. Best of luck.
I live in the USA and will be spending 6 days in Edmonton in August. My Verizon plan doesn't include any international roaming/data benefits, and I don't want to call Verizon and risk them forcing me to "upgrade" my ancient plan to a current plan (i.e. more expensive, less benefits) in order to get roaming. I only need it for a week anyway!
The other thing I was thinking was just to turn my Rezound radio off and buy a pre-paid phone from a local Wal-Mart once I arrive, and only use my Rez on Wi-Fi. Someone suggested I buy a pre-paid SIM with a small data allowance and pop it in my Rezound. Will that work without a Global ROM?
I've never needed to deal with this situation before, what should I do? I want to avoid modifying my plan if at all possible. I think buying a temporary pre-paid phone is the best option...
Thanks!

yes but you can buy just the sim card for alot cheaper than buying a phone with sim in it...i only ever really used the rezound here in the USA with a gsm network with no issues...

Ok, so I guess the main question then: I'm running CM10.1, does that ROM work in Canada or do I need a "Global" patch of some kind?
Actually it's a moot point - the company I'm working with up there will provide me with an iPhone for the week! :good:
I recently visited Canada with my Rezound (CM11) and regular US plan. The following are some potentially useful notes:
Verizon users can use SMS (to US numbers) while in Canada at no additional charge. Soon after crossing the border, Verizon automatically sent me a SMS confirming this.
Before crossing, I turned off mobile data and kept it off until I got back.
MMS messages use data, so there would be an additional charge. Disabling data also blocks notifications that a MMS message is available.
I forgot if I had to select a different network setting (CDMA, GSM, etc). However, I had no signal issues once I had the right setting.
I use Google Voice. When I had access to WiFi, I could check voicemail and from my laptop I could place calls (to US or Canada numbers) for free.
Since I have used the sony Z2 on us T-Mobile I have not seen the phone roam at all. Here is where my question is. Last Sunday I was fishing in international water and I noticed I lost signal about 12 miles off shore. My friend who had an Att phone still had signal. At one point I did a "mobile network" check. Roaming was checked off. And then when I searched verizon and att both came up but it would not let me connect to any of those networks. So it is almost like the phone will not let me roam. Am I missing something? Is there a way to check for international roaming? Is it because my phone is rooted with boot loader unlocked. Or is this something with t mobile. Phone model is d6503 and I am on the simple choice (credit check) plan. I will be traveling internationally throughout the year and I want to make sure I am not going to have any issues connecting to networks. Thank you in advance for your help on this
